COUPLING.

Specification of Letters Patent.

Patented July Ml, 11917.

Application filed June 15, 1915, Serial No. 34,199. Renewed October 4, 1916. Serial No. 123,764.

To all whom it may concern:

Be itknown that I, EDWARD F. BERRY, a citizen of the United States, residing at New Orleans, in the parish of Orleans and 'State of Louisiana, have invented certain new and useful Improvements in Couplings, of-which the following is a specification, reference being had therein to the accompanying drawing.

This invention comprises improvements in couplings, capable of various uses, as will be apparent to persons skilled in the art to which the invention pertains.

An object of the inventionisto provide an improved simple coupling means, particularly useful'in expeditiously securing the members to be coupled in closed relation; preferably Without the use of rivets or bolts; and the same, in combination with means for locking the parts in assembled relation.

More specifically, the invention embraces a coupling including interfitting wedge parts adapted, when relatively turned, to

draw the members together, and means for positively forcing said relative turning movement to correspondingly more effectively secure the mutual operation of the wedge parts for the purposes stated, as well as to lock the parts against accidental separation.

Improved details in the construction and arrangement of parts will be apparent from the specific description hereinafter contained, when read in connection with the accompanying drawings forming parts hereof, in which,

Figure 1 is a sectional pipe coupling;

Fig. 2 is a plan view showing the manner of passing the wedge lugs through the clamping ring just prior to the turning of the ring and the screwing up of the locking means. 7

Fig. 3 is a side elevation; and

Fig. 4 is a-longitudinal sectional view of view through the 'Fig. 3 on aline through a pair of wedge parts, the wedge ring being here shown as turned into clamping position with the looking means screwed home.

Referring more specifically to the drawings, wherein like reference letters designate corresponding parts in the several views, A and B represent respectively, oppositely "disposed coupling members, adapted to be secured to adjoining ends of a pair of pipe sections desired to be united together.

The coupling members A and B, having outwardly extending flanges C and D between which a suitable packing ring E of fibrous rubber or other suitable composition carried by one of the flanges and projecting therewithout to engage the surface of the.

through the slotted portions F, the flaring mouths f of the slots assisting in the operation just referred to.

Loosely overlying the flange D, is a flat ring H provided with slots it, through which the lugs G also pass, said ring carrying outwardly projecting curved wedges J, corresponding in. number to the wedge lugs G and having inclined faces F, adapted to be engaged by the inclined under edges 9 of the heads of the lugs G, so that upon turning of the ring, the two coupling members A and B are tightly drawn together and the surfaces thereof forced into abutting relation., The ring H is held against displacement on the coupling member B-by a set screw K engaging the coupling member B.

To secure a positive turning movement of the ring H with its wedges beneath the beveled heads of the wedge lugs G, I pivotally secure at L, to either one or more of the lugs J, a clamping bail M, the arms of which are adapted to receive therebetween the curved cooperating lugs J and G when engaged,-the bail being curved in keeping with the contour of the latter,and the closed end m of the bail being adapted to lie behind the wedge lug G, where a clamping bolt N, passing through said closed end of the bail, mav engage the back of the lug and thus force the wedge parts together, this bolt constituting an effective lock to prevent separationor loosening of the parts.

Where found desirable the back of the wedge lug G may be indented or recessed, as

.at n, for the reception of the end of the clamping bolt N to prevent slipping of the bail off the lug The'clamping bolts N are provided with perforated head portions n a through which any convenient implement may be inserted for turning the bolts, this arrangement being suitable for compactness and to facilitate turning of the bolt, while enabling close proximity of the latter to the ring H. Other forms of bolts and means for turning the same may of course be resorted to, Where feasible.

From the foregoing description, it will be appreciated that in a simple and inexpensive manner I have provided a coupling which is readily detachable, but which at the same time may be quickly assembled and firmly locked together in a substantially permanent coupled position, as occasion may require. I

While I have herein shown a number of the locking bails which will enable the manipulation bf any one of the same in keeping with the convenience or position of the operator, and while all of the bails when secured in, place will additionally lock the parts together, it will be understood that it is necessary only to provide a single bail or to clamp'in place but one of the bolts to secure a practical operative combination.

It will also be appreciated that whereas I have herein disclosed a specific embodiment of my invention, the same is capable of embodiment in other forms and devices as may be in-keeping with the hereto appended claims.
